Guy Fieri samples fast food done right; In Houston, TX a joint in an old grocery store for wild burger toppings; In Milwaukee, a corner café putting a twist on classic; And in Reseda, CA, hot dogs deep fried, wrapped in bacon and even in burritos.

Guy Fieri rolls out for great foreign flavors: Scandinavian cooking at a place in Chicago, from meatballs with lingonberries to house-cured gravlax; Middle Eastern favorites at an old drive-in in Arlington, Texas, from falafel to pilaf; and authentic Mexican cooking in Guy's home town, Santa Rosa, Calif., from homemade tacos to sopas.
